Safety 1st Continuum Review – Best 3 in 1 Car Seat?

Anyone who has researched car seats knows that most of the options available will only fit your child for a limited time. While researching car seat options for our child, we found the 3 in 1 seat, which is a combination car seat in terms of value and use in our opinion.

The Safety 1st Continuum 3 in 1 car seat is a car seat that can grow with your child. It works for rear-facing up to 40 pounds, forward-facing up to 50 pounds, and is a booster seat up to 80 pounds. This helps provide your child with that additional protection for the same price as many other car seats on the market. 

The Safety 1st car seat had all of the features we were looking for. Not only did it grow with our child, but we got choices on how it reclined, it fits well in our vehicle, it gave some more legroom for our child, and it was easy to clean!

What is the Safety 1st Continuum 3 in 1 Car Seat?

The Safety 1st car seat is the perfect seat to grow with your child. We loved that we got three car seats in one and for the price of some of the higher-end car seats that only work for one stage with your child.

This car seat is designed to work in three ways, with just some slight adjustments to make this happen. We bought it when our child was first born and was able to use it until they were ready to graduate out of a booster seat and into a regular car seat.

This car seat is comfortable and has all the additional features that you need to help your child stay safe and comfortable in the car seat. The harness holders make it easy to get the child in and out, the reclining positions can change with your child, and the cup holder and material are easy to take out and clean.

While other car seats only last for a few years, the Safety 1st Continuum 3 in 1 car seat has all the great features you need to last a long time.

How Does This Car Seat Work?

The Safety 1st Continuum 3 in 1 car seat works as three car seats in one. It is designed to work as a rear-facing seat, a forward-facing seat, and a booster seat as your child grows.

As soon as you bring your baby home, you can start to use this car seat. It is designed to work as a rear-facing car seat for children 5 to 40 pounds. There is additional legroom so your child can stay rear-facing for longer.

Once your child is ready, and at least two years old, you can turn this car seat into the best forward-facing seat around. This is designed to work for children 22 to 50 pounds so your child will stay safe for longer.

While many car seats stop here, we picked this car seat because it lasted a little longer and turned into a booster seat as well. Once your child is four years old, they can move into the booster part of this seat. It is designed for children between 40 to 80 pounds.

Key Features

Safety 1st 3 in 1 Continuum car seat provides a lot of features that we loved. It is a car seat that does the job, plus a lot of extras, to make sure you have something that you feel safe putting your child in. Some of the features you are sure to love include:

It Grows with Your Child

The Safety 1st Continuum car seat can grow with your child. You can start with the car seat rear-facing. This is designed to work for children between 5 and 40 pounds. Once your child’s head gets higher than the headrest, it is time to turn them around.

At that time, this car seat can turn around and still provide protection. As a forward-facing car seat, this option can utilize the harness mode and hold your child until they reach 50 pounds. Your child should be at least 22 pounds and 2 years old before turning the car seat around.

Once your child is at least four years old and 40 pounds, you can turn this car seat into a belt-positioning booster. This helps you to get at least four or more years out of this one car seat.

3 Recline Positions

3 Recline Positions

Safety 1st 3 in 1 car seat offers three different recline positions to help provide more safety for your child. Two of these are used for rear-facing children and one when the car seat is used for forward-facing children.

The two rear-facing positions allow your child to grow into the car seat. Use one recline for the smaller child who needs more care and protection along the way. As they get bigger, it is easier to change the recline position to help your baby sit up more.

Removable Parts for Easier Cleaning

The Safety 1st car seat doesn’t have a lot of parts that come off that are dangerous. But all the high-traffic areas that easily get dirty can be cleaned off without a problem.

The removable cup holders come right off and can fit safely in your dishwasher. It is also possible to take off the material of the car seat and get that cleaned off when necessary.

Harness Holders

The Safety 1st car seat provides some easy harness holders to use. These can be held back so it is easier to get any child out of the car in no time.

The QuickFit Harness is a useful feature that we used a lot to make things faster. It is designed to make it easier to adjust the headrest and harness in just one step which was a lifesaver for us.

Alternate Products to Try

A good alternative to the Safety 1st 3 in 1 car seat is the Graco Extend2Fit Convertible seat. This one allows a little more weight while remaining rear-facing which does provide some more protection. It also has a good deal of legroom to do this and can convert into three different seats.

The forward-facing option on this one can also hold a little more weight. If safety is your top priority and you want to ensure your car seat can meet your expectations for safety, the Graco Extend2Fit car seat maybe a little better choice.

What We Liked/Didn’t Like

The Safety 1st Continuum 3 in 1 car seat provides a lot of great features to love. Our family found it was perfect for our needs and helped us to know our child was safe no matter where we had to go.

However, there were some good things and some challenging aspects of using this car seat at times. This is what we found:

The Good

The Safety 1st Continuum car seat has a lot of benefits that worked well for our family. We liked all of the features we talked about above, but a few options that stuck out to us include:

  1. This car seat provided a lot of legroom. This allowed us to keep our child rear-facing for longer than we would have with another car seat.
  2. It provided a good deal of protection for an affordable price.
  3. The fabric was durable enough to add to our washing machine without ruining it. This is a plus since our child is pretty messy.

The Bad

The Safety 1st Continuum car seat was relatively easy to use, though we did struggle a bit with the installation. When using a seat belt to help hold this in place, the path for the blet was a little narrow.

This made it hard to thread the seat belt through the whole path and make it secure. This also provided some challenges when we tried to tighten the seat belt for more safety.

While this wasn’t a big issue in our vehicle, we did notice that the base is longer on this car seat than some others. Because of this base, it may not be able to stay level with the seat of the vehicle.

You should double-check that you can get a good installation going without all the concerns. This will help prevent the car seat from slipping and sliding.

Despite these two issues with installation, we found that this car seat is safe and easy to use. The user will need to take some extra time to ensure the car seat is steady and installed properly before putting their child inside.

The Safety 1st Continuum 3 in 1 car seat provided everything our family needed and more. It grows with our child, allowing us to get the most out of our money with three car seats in one while knowing our child was safe the whole time.

We enjoyed that this car seat was easy to clean, that it had extra safety measures in mind, and that it allowed for some extra legroom so we could choose how long to keep our child in each seating position. For the price, this Safety 1st car seat provides everything you need!
